How do bug zappers work

The sounds of Spring. Rain and thunderstorms, birds that are finally coming back after a long winter, and ZAP!

To investigate the effectiveness of bug zappers on mosquitoes, the Department of Entomology and Applied Ecology at the University of Delaware spent 10 weeks analyzing bug zappers. Altogether, over 13, insects were zapped and collected. Out of 13, zapped insects, l ess than 0. Out of 13, zapped insects, o ver Based on the study's results, bug zappers are killing beneficial insects like beetles and moths, which can result in negative effects on local ecosystems. Experts and studies from Colorado State University Extension and the American Mosquito Control Association concluded that bug zappers are not effective at controlling biting mosquitoes.

A bug zapper , more formally called an electrical discharge insect control system , electric insect killer or insect electrocutor trap , is a device that attracts and kills flying insects that are attracted by light. A light source attracts insects to an electrical grid, where they are electrocuted by touching two wires with a high voltage between them. The name comes from the characteristic onomatopoeic " zap " sound produced when an insect is electrocuted. Bug zappers are usually housed in a protective cage of plastic or grounded metal bars to prevent people or larger animals from touching the high voltage grid. A light source is fitted inside, often a fluorescent lamp designed to emit both visible and ultraviolet light, which is visible to insects and attracts a variety of them. The light source is surrounded by a pair of interleaved bare wire grids or helices. The distance between adjacent wires is typically about 2 mm 0. A high-voltage power supply powered by wall power is used, which may be a simple transformerless voltage multiplier circuit made with diodes and capacitors which can generate a voltage of 2 kilovolts or more. This is high enough to conduct through the body of an insect which bridges the two grids, but not high enough to spark across the air gap. Enough electric current flows through the small body of the insect to heat it to a high temperature. Many bug zappers are fitted with trays that collect the electrocuted insects; other models are designed to allow the debris to fall to the ground below. Some use a fan to help to trap the insect.

Spring is here.

While you have fun outdoors, many insects get to enjoy a good meal. Either they're eating your food or they're eating you. To clear your yard of these insects, you can try a variety of devices, ranging from simple Citronella candles to elaborate traps to pesticides such as Dursban to electronic bug zappers. A bug zapper , more formally known as an electronic insect-control system or electrical-discharge insect-control system , lures bugs into it and kills them with electricity. In this article, we will examine the parts of a bug zapper, learn how this device works and discuss the controversies surrounding its use.

Fly zappers have long been a popular method of fly control in commercial food handling premises such as take away outlets, cafes, delis, butchers, bakeries, commercial kitchens, food manufacturing and more. In fact, the fly zapper has been around for centuries with the first fly zapper believed to have been invented by Leonardo da Vinci in The first commercially produced fly zapper was invented in They get the name from the characteristic 'zap' sound created when an insect touches the electrical grid. Fly zappers are available in a range of different shapes and styles but all share the same basic characteristics. Fly zappers use ultraviolet tubes to attract flying insects into the unit, before 'zapping' them dead when they touch a high voltage killing grid. UV tubes attract flying insects by emitting a wavelength of light attractive to flies.

As the bug flies toward the light, it penetrates the space between the wire-mesh grids and completes the electric circuit. When the insect sees the UV light from the bug zapper bulb , it enters the space in between the mesh grids. Tools Tools. To investigate the effectiveness of bug zappers on mosquitoes, the Department of Entomology and Applied Ecology at the University of Delaware spent 10 weeks analyzing bug zappers. The device is powered by a propane tank, so no electricity is required. What is dioxin? Sign up for our Newsletter! Most Zappers use fluorescent light bulbs that emit ultraviolet light to attract the insects. Mobile Newsletter chat close. The air around the bug zapper can become contaminated by bacteria and viruses that can be inhaled by, or settle on the food of people in the immediate vicinity. Look for ONE of the following active ingredients on the label that is safe and effective against biting insects and the diseases they can transmit! Until then, we can only dream.

Kansas State University. Based on the study's results, bug zappers are killing beneficial insects like beetles and moths, which can result in negative effects on local ecosystems. When we exhale, we emit CO2, which a female mosquito can detect from far away. Search: Go! And these are only a few examples of what we found. Most Zappers use fluorescent light bulbs that emit ultraviolet light to attract the insects. Current Microbiology. What is dioxin? PMID Cart 0. It is an effective mosquito repellant in high concentrations, but individual plants do not make enough oil to be effective. The Best Bug-Killing Gear. Since mosquitoes lay eggs in water, you should eliminate all sources of standing water , such as watering cans or old tires. Iowa State University.
